I would deburr and champfer a piece of brass that you know will shave a bullet. If that works, then you found your problem.
If it is new brass I would not trim, yet... I would deburr and champfer all the new brass, load it and fireform it. Then I would set my die up to bump .002" and then trim just enough off to square it all up and deburr.
